Quick Selection Guide
Horizontal Ionizing Air Blower is a member of the United SCP
ElectraFlow ESD Ionizer family. The SL-028 blower is a wide area
unit designed to provide total coverage of an area of
approximately 24" x 48" and is used to control the
accumulation of static electricity on electrically
insulative surfaces and objects. The unit is
equipped with an on demand heater used to reduce
thermal shock syndrome prevalent with the
manufacturing of certain items.
Please read the complete
instruction manual before operating the device. This unit is
equipped with a 3-wire grounding plug and must be plugged into
a 3-terminal grounded socket. Do not modifying plug or using an
ungrounded power socket. If an extension cord is necessary, use
only a 3-wire extension cord that provides grounding.

Internal repairs or
servicing should be done by PC personnel.

The PC Ionizing blower should be located above work
surface. There should be no cross flow of air between unit and
work surface. Drafts from air conditioning and heating air
outlets can affect performance of this unit.
The SL-028 unit may be mounted using adjustable mounting brackets.
The mounting brackets are designed for use on a variety of
The SL-028 requires 220 VAC 50Hz/110VAC 60Hz.For proper operations.
The unit must be grounded for safe operation. The unit is
supplied with a standard heavy duty 3 prong (US
Style) plug. The color code for wiring the
plug is as follows: Red-line; Blue-Neutral; Green/Yellow-Ground.
Activate the SL-028
Horizontal Ionizing Air Blower by turning FAN SPEED knob
clockwise, out of the off position. The IONIZATION INDICATOR
will illuminate to indicate the presence of ionized air. Set
airflow as desired by adjusting FAN SPEED knob. If warm air is
desired for operator comfort, turn on heater by setting heater
switch to the on (1) position. TO clean ion emitter points,
glide POINT CLEANER knob right and left.
The time required to
neutralize a static charge on an item in the air stream depends
on fan speed. Setting a higher fan speed reduces time required
to neutralize a static charge. When using the SL-028
unit in an electronics assembly area, the ionized air stream
should cover as much of the work area as possible. The constant
flow of ionized air will prevent items such as work surfaces,
tools, materials and components
from developing a static charge. Charged items introduced into a
work area will be neutralized and will remain neutral while in
the ionized air stream.
SL-020 horizontal ionizer has been designed for minimal
maintenance. The only regular maintenance suggested consists of
emitter point cleaning, ion balance checking and ion output
checking. Emitter point cleaning takes only moments with the
point cleaners. The SL-028 contains an advanced self balancing circuit
that compensates for
emitter point wear, line voltage fluctuations and variations in
Scheduled checking of ion
output and balance should be considered to assure quality audit
requirements however the units are extremely low maintenance and
4.1 Emitter Cleaning
To clean ion emitter
points: simply rotate point cleaner knob located at center of
each outlet clockwise to the stop (approximately one turn) and
release. The spring-loaded point cleaning brush will return to
its home position.
4.2 Air Inlet and
The air inlet grilles on
the top of the unit and ionized air outlets should remain clean
to prevent restriction of airflow. They can be cleaned with a
soft brush or vacuum.
4.3 Ion Output Check

may damage balancing circuit.

Ion output of the
United SCP SL-020 unit is inherently balanced by design. As
a result, there are no calibration adjustments, If, after
checking ion balance as outlined in Section 4.4,an unbalance or
offset voltage exists in excess 0V +/- 10V, contact United SCP Customer Service
